## Summary description

The BenQ LW890UST is a DLP projector with 4000 ANSI lumens brightness and WXGA resolution. It features a laser light source with a lifespan of 20000 hours, manual focus, and a fixed focal length of 6.9 mm. It supports various 3D formats and has multiple graphics resolutions, making it suitable for both educational and entertainment purposes.

## Long description

The BenQ LW890UST is an ultra-short throw DLP projector with 4,000 ANSI lumens brightness and WXGA (1280x800) native resolution. Designed for education and collaborative spaces, it uses a sealed BlueCore laser light source with a 20,000-hour life, DustGuard™ protection, and a hermetically sealed DLP chip to deliver consistent picture quality and low maintenance. The fixed 6.9 mm focal length and ultra-short throw optics enable large images from a short distance, reducing shadows and glare in classrooms.
Advantages
Precision-aligned BlueCore laser diodes and a secondary yellow-infused dual color wheel increase light efficacy and reproduce richer RGBY colors while maintaining 4,000 lumens. The hermetically sealed DLP chip and sealed laser module resist dust and heat for long-term reliability, and the projector offers instant power-on with minimal setup time. High native contrast (100,000:1) and sealed optics provide sustained brightness and deep blacks suitable for bright classrooms. Network control compatibility and centralized firmware tools simplify maintenance for IT administrators.
Suitable for
Classroom and lecture halls where ultra-short throw projection reduces shadows and glare
Interactive learning environments using PointWrite™ multi-touch and PW40U module
Institutions requiring centralized network control and remote maintenance
Large, bright rooms needing high-brightness projection with lights on

How to use
Mount the LW890UST close to the projection surface using the recommended ultra-short throw wall mount or place it inches above the screen to obtain the intended large image without shadows. Connect to a computer via HDMI or USB for PointWrite™ interactivity; the PointWrite™ module auto-calibrates when plugged into a PC USB port. Use network (LAN) or RS-232 connections for centralized control and monitoring by school IT staff. For multi-user interactive sessions, enable PointWrite™ multi-touch or add a second PointWrite™ projector to expand the drawing surface.
Usage recommendations
To maintain long-term brightness and image quality, keep the laser engine sealed and follow administrator procedures for centralized firmware updates via BenQ MDA. Install in a location with minimal dust exposure and use network control features (Crestron, AMX, PJ Link, Extron IP Link) for scheduled power management and monitoring.
